TO ALL WHOM IT MAY CONCERN:

Be it known that I, THEODORE C. SAcHsE, of Ohicago, in the county of Cook, and State of Illinois, have invented a new and useful Improvement in Pessaries; and I do hereby declare the following to be a full and correct description of the same, suflicicnt to enable others skilled in the art to which my invention appertains to fully understand and use the same, reference being had to the accompanying drawings, which make part of this specification, and in which- Figure 1 is a bottom view of myimproved instrument Figure 2 is a side elevation of the same. 7 v

Figure 3 is a similar view, with the key inserted, and a diiferen position given to part of the instrument Figures 4 and 5 are plan views of figs. 2 and 3.

Similar letters of reference indicate corresponding parts of the several figures.

My invention consists in the peculiar concave shape of the bowl, which will form, with its perfectly concave smooth surface, a bearing, to which the neck and mouth of the uterus can conform itself naturally and without anyirritation; also, in providing this peculiar-shaped bowl with a stem, the upper part of which is semi-diagonally curved, and forms the bearing for an auxiliary stem, moving within and curved like the main stem so as to either form one curve with the latter, or to be moved toa right angle with it.

A, in the drawings, represents the bowl, having an oblong-shaped concave face, from the centreof which rises the hollow stem B, the upper part of which is semi-diagonally curved, as shown at 13. Within this stem moves another stem C, curved at its upper part similarly to the part B, and provided with a pin, 0, which moves in a slot, 6, in the main stem 13. The slot 6 is so situated that when the pine is at either end of its extremities the stem 0 will either be in position, as shown in fig. 2, that is to say, resting in the concave surface of the part B of the stem B, or at right angles 'to it, as shown in fig. 3. The stem 0 is holl0w, and provided at the point where the curve begins with an opening, d, and its lower end is made square, into which fits the square end of the key D, by means of which the stem 0 is moved to either position above described.

In introducing the instrument, the'operator inserts the key to serve'as a director, places the index-finger of the left hand against the key, close to the bowl, placing the thumb of the left hand on the flat part 0 of the key; uses the right hand conieally, well oiled, resting the curve of the tube on the indexfinger of the right hand, and slides the instrument gently through the 0s uteri. The key is then extracted or withdrawn. Should within three days the instrument become expelled or drop through the dilated 0s uteri for want of contractibility of the 0s uteri, the surgeon inserts the key again, and by gently turning it with his left hand to the right brings the tube C to a right angle with the tube 13, which forces the instrument to remain in sz'tzt without the slightest irritation. In case of thorough relaxation of the faseiae, when medical treatment has eflected eontractiom the uterus is held in its normal state by means of this instrument-without in any way causing irritation, and when the cure is perfected the instrument is withdrawn;

' All pessaries that have heretofore been invented have by practical experience proved to be of an irritating character, especially where there was the slightest inflammation of the uterus. This instrument will hold the uterus in its place without the arms or stems touching the uterus, the 0s uteri sinking into the concavity of the bowl, and in conforming itself to its shape. holds the same by suction, the spread arms or stems balancing the bowl. In cases of predisposition to polypi of the uterus the instrument prevents the growth of the same. In retroversion of the uterus, where thereis in all cases a strong predisposition for the organ to relax, this instru ment scientifically and carefully applied, after replacing the uterus into' its proper position, will hold the uterus in positionl In cases of incipient metritis, chroniccnlargcment of the uterus, which has prolapsed the organ I through its increased intrinsic gravity, superior advantages are derived from the use of this instrument by holding the uterus in its proper position and preventing it from relapsing. In prolapszts uteri, with scrofulous sanio'us discharges from the uterus, or leucorrhoaa, this instrument is of equal value.

This improved pessary can only be safely used by skillful and experienced obstetricians, and as such is an instrument ofi-ered to the profession and not to the general public. i i

The catameni-al' discharges can escape through the hole at and tube 0.

Especially for the above as well as for all other purposes the instrument should bemade of either fine silver or gold, and witha perfectly smooth surface, and as it does not in any case touch the uterus with its arms, which serve only to balance the bowl, no irritation can take place.

What I claim as new, and desire to secure by Letters Patent, 1s-

1. The oblong concave face of the bowl A of a pessary, substantially as and for the purposes described.

2. The curved part B of the stem 13, formingan automatic means of holding the instrument in position, substantially as and for the purposes set forth.

3. The auxiliary stem O, withits curved part 0, opening d, and square lower-opening, moving within the stem B, substantially as and for the purposes described.

4. A pessary, substantially'as described, operated by a key, D, substantially in the manner set forth.

The above specification of my improvement in pessaries signed-this eighth day of October, 1867.
